when was the last time your MC been Tune Up??
Maybe the tappet was the problem
also the valve clearance

I already adjusted the valve clearance according to the required settings but still i hear the noise

I already corrected this problem the issue is need to adjust the valve in to tight clearance for 10mm on intake and 15mm on exhaust now the noise becaome tolerable like new this might because of worn tuppet screw need to replace it already.

Next problem was the hard staring but for my first conatinment action was to replace the head gasket hope it will be successful this saturday.

Why became hard starting?

This is because of coolant escaping on the head gasket and flowing into the combustion chamber leaving the spark plug fouled with coolant and hard for the gasoline to beh burn. Need to flood it up with gasoline to fire it up.

This happens to me several time every ride about 10 to 20 mins stopped after ride it is hard for it to fire up.

Will update this soon when i check the engine tomorrow morning widh me luck

already done

problem fixed.

its the gasket was the culprit with my problem hard starting.

i am right coolant coming from leak gasket reason to hard to ignite the gasoline into the chamber. already replace head and base gasket to make sure there will be no leak.

lesson learn here is make sure to focus when changing piston, cylinder etc. since this is the major life of the engine to start it make sure always clean.


next just found some scratches on my cylinder wall and piston. before i ask my mechanic why is there a scratches on my piston and cylinder wall both upper and lower. he said it is normal.

i don't think so maybe i have to do some tweaks to prevent scratches since the only one should scratch it is the rings. i am thinking on modifying the piston.

i will keep you updated with this thread when my plan was successful.
